Corrective maintenance Report, locate, and eliminate faults quickly System diagnostics with PROFIBUS DP and SIMATIC Our PROFIBUS DP diagnostic products and functions meet the growing demand for maintenance brought about by increasingly decentralized automation concepts. Diagnostic repeater In addition to traditional repeater functionality, the Siemens diagnostic repeater provides functions for localizing faults in bus cables, such as open circuits, short circuits, Shortages to the shielding as well as missing terminating resistors. SIMATIC system diagnostics PROFIBUS diagnostics are an integral component of the STEP 7 HW-Config diagnostic functions, the CPU diagnostic buffers and the STEP 7 "Report system fault" function. PROFIBUS diagnostic package The PROFIBUS diagnostic package consists of a function/data block as well as diagnostic displays for the more popular SIMATIC HMI devices. Free package download
